Seabook

Seabook supports people who need maritime information while studying, working at sea, or reviewing procedures before a task. It presents nautical subjects in a format that fits everyday phone use, so you can check information without carrying several printed references. In addition, the Seabook APK can be useful when an internet connection is limited, because the app is designed around onboard and learning situations where access may change during the day.

Main Seabook Features

Offline maritime reference

Seabook gives you access to maritime knowledge that can be used during training, onboard review, or personal study. Because the app supports offline use, you can keep important reference material available when a signal is weak or unavailable. This makes it practical for users who need to review information during watches, lessons, or preparation time.

Navigation and ship topics

Seabook covers common subjects that marine professionals and students often need to revisit. You can read about COLREG, ship stability, navigation, marine engineering, GMDSS, meteorology, and ship management. As a result, the app works as a single reference point for several areas that are usually studied across different manuals.

Safety related content

Seabook also includes material focused on safety at sea. You can review personal safety, shipboard safety, first aid, fire fighting, risk assessment, search and rescue, and piracy at sea. These sections are useful when you need a reminder of basic procedures or want to refresh knowledge before drills, training sessions, or onboard duties.

Nautical calculators and conversion tools

Seabook provides tools for calculations that are common in navigation and seamanship. You can use unit converters, sight reduction, rhumb line, great circle, dead reckoning, CPA, and wind calculators. Instead of moving between separate notes and tools, you can keep these practical functions in the same app while working through a problem.

Maritime language and business references

Seabook includes reference material for communication and maritime operations beyond navigation. You can check maritime English, SMCP, ropework, signal flags, country flags, chartering, PSC, INCOTERMS, and maritime business topics. This helps users who need to understand terms, signals, or commercial expressions during study or professional review.

About Seabook Content

Seabook has been available as a maritime app since 2013. Its content was created by Captain Ozgur Dogan Gunes, a Master Mariner with onboard experience and senior shore based maritime experience. This background matters because the app focuses on practical reference needs that appear in maritime education, daily ship operations, and professional refreshers.

For users comparing options before installing the Seabook app, the main value is its mix of reference reading and working tools. It is not limited to one subject area, and it is not only a calculator app. Instead, it brings together study material, safety topics, communication references, and nautical tools in a phone friendly structure.

Seabook Master Option

Seabook Master is an added option for users who need more than the standard app content. It adds enriched content, use without ads, and more powerful computational tools. This can matter for users who rely on the app often during education, onboard review, or repeated navigation practice.

How to Use Seabook on Android

After you download Seabook, start by opening the app and choosing the area that matches your current need. The Seabook latest version is arranged for quick checking, so it helps to begin with a subject or tool instead of browsing without a purpose.

1. Open Seabook on your Android phone and review the main categories shown on the home screen.
2. Select a topic such as navigation, safety, GMDSS, marine engineering, or ship management based on what you need to study or check.
3. Read the related reference notes and use the graphics when they are available to understand the topic more clearly.
4. When a calculation is needed, move to the tool section and choose a calculator such as CPA, dead reckoning, wind, sight reduction, rhumb line, or great circle.
5. Keep the app available for offline review during training, onboard preparation, or personal study sessions when internet access may not be stable.
